To all whom it rhay concern:

Be it known that we, THOMAS E. MURRAY- and ARTHUR V; A. -MOHARG, citizens of the D-STATES-PATENT THOMAS ELMUR AY AND ARTHUR v. A. McI-IARG, or riEw. YORK, 1v. Y.

DEMOUNTABLE VEHICLE-WHEEL.

United States, residing at New York, in the county of New York and State of New York,

.have invented a certain new anduseful.Im-

provement in Demountable Vehicle-Wheels,

of which the following is-aspecification.

nave. v

. In the accompanying drawings-5 Figure 1- is an elevation of the front end of the hub, and front side of'the wheel nave, showing the locking device engaged. Fig. 2 is 'a diametral section ofthe .same. Fig. 3 is an edge view of a portion of the looking plate. r

Similar letters of reference indicate like A represents the nave portion of a vehicle wheel, preferably made hollow and of sheet metal. v,The hub has a rear flange C, a cylindrical portion D, upon which' the have A is received, and an outer threaded por- Entering circular openings in the walls ofthe nave A are a number of studs F. Each stud is cylindrical over. the greater portion of may be cylindrical and threaded to receive V a nut I. The shoulder on the stud bears on one side of flange. C, the fastening nut I bears on the other side of said flange, and .the shaped portion G fits in the correspondingly shaped opening extending. through said flange. In this way, thestuds are secured to said flan e and protrude from the front face thereo so thatwhen the wheel nave A is placed upon the hub they pass through the openings in said nave. Said studs also pass through openings in an annular plate J which is placed upon the hub Specification of Letters Patent. Pajbented luau 13, 191 '7,

and in contact with the front face of the nave A. In the portion of each stud which 1 protrudes beyond theplate and in the curved side-thereof is formed a transverse undercut recess; K is-an annular locking disk, which is rotatable upon the hub.v On the 'outerface of diskK and at the circumferential"dge thereof are as manycani projec- The invention' relates to demountable ve; hicle wheels, and consists inthe construction whereby the wheel-"nave is locked to studs extending from a hub flange through said tioii s.--L as thereare studs F, e'ach projection having an inclinedfaceM. In the air- J. The locking disk K is then rotated on thejhub so as to bring the projections L into the undercut recesses in studs F. In this'way,

thelwheel nave A is locked upon each stud,

andthe said studs are locked together, andby reason of the inclined faces of the cam pI-O]6Ct101'lS, tl1(-) locking disk clamps the nave tightly; against the hub flange C. A

headed bolt 0 isfinally passed through one of the openings P in looking disk K, and its threaded end engages in an opening in plate locked is prevented. The object of provid- ,by which meansany rotation of the lockmg plate on the hub after the' parts are ing several-openings P1 in the locking disk.

K is-to allow: for any irregularities of. construction or fdisplacements due towear, which might-bring a single opening, if there were but one in said disk, out ofregistry with the openingin plate J. For convenience inrotating thelocking disk, I provide notches Q communicating with two diamet-' rically'"opposite'recesses N 'in' the locking :disk K, iii-which notches may be inserted the points of a suitablespanner. The object of making the portions'G of the studs polygonal,':or with, as here shown, a,- flat side, and

of placing the openingswith their corresponding 'flat sides toward the circumference-o flange C, is to insure that the studs shall be properly placed to bring their recesses into'position to be engaged by the cam projections L on thelocking disk K.

We claim 1. A demountable vehicle wheel, ,comprising a hub, a flange thereon, an'annular plate on said hub, a wheel nave interposed-between said flange and said plate, studs on said flange extending through openings in said nave and said plate and havingtransrerse undercut recesses on their protruding portions. an annular locking disk disposed on said hub in front of said plate and Ca n projections on the front site of said looking disk entering said stud recesses to lock together said disk and said studs. 4

A deniountable vehicle Wheel, comprisin a hub. a flange thereon, an annular plate on said huh. a wheel nave interposed between said flange and said plate, studs on said flange extending through openings in said nave and said plate and having transverse undercut renesses on their protruding portions, an annular lot-king disk disposed on said hub in front of said plate, cam projections on the front side of said locking disk entering said stud recesses to lock together said disk and said studs, and'mea-ns for securing said disk and said plate in locking engagement.

in testimony whereof We have aflixed our signatures in presence of two Witnesses. THOMAS MURRAY. ARTHUR V. A.-M0HARG.
